The JAK/STAT pathway contributes to control gene expression,cell growth,proliferation,differentiation,apoptosis and immunoregulation.Recent studies have found that the JAK/STAT pathway was closely related to the occurrence and development of lymphoid neoplasms.The study of JAK/STAT pathway could lead to new treatment strategies for lymphoid neoplasm treatment.

Objectives This study was designed to observe the correlation of the levels of serum N-terminal pro-brain natriuretic peptide(NT-proBNP) and high sensitivity C-reactive protein(hs-CRP) between the 3rd day after acute myocardial infarction(AMI) and after 3 months of left ventricular remodeling(LV remodeling) and to establish the predictive levels of NT-proBNP,hs-CRP for LV remodeling after AMI.Methods The blood samples from 106 patients with the first AMI and echocardiography were examined on the 3rd day and after 3 month.LV remodeling was estimated by the changes of left ventricular end-diastolic volume(LVEDV) during the 3rd day and after 3 month.Based on the change of LV remodeling,the 106 patients were divided into two groups:LV remodeling group(defined as the change rate of LVEDV more than 20%) and non-LV remodeling group.Results The correlation coefficients of the change of LVEDV were 0.706 for serum NT-pro BNP and 0.596 for hs-CRP.With a cutoff value of 0.20,the area under the ROC curve(AUCs) was(0.892) for NT-proBNP and 0.825 for hs-CRP.There was no statistically difference between NT-proBNP and hs-CRP.The ROC plot indicated that NT-proBNP was superior to hs-CRP for predicting LV remodeling.Conclusion The level of serum NT-proBNP appropriately reflects LV remodeling after AMI and shows more efficacious than the level of serum hs-CRP.The level of serum NT-proBNP on the 3rd day after AMI and LV remodeling were positively correlated with the level after 3 months.

Objective To investigate the prevalence of metabolic syndrome in patients with maintenance hemodialysis, and to analyze the potential risk factors. Methods The clinical data of 472 patients with maintenance hemodialysis from 7 blood purification centers were collected. Patients were divided into the MS group and the non-MS group. The demographic data , anthropometric examinations , dialysis prescription and results of laboratory were compared between these two groups. Multivariate Logistic regression analysis was performed to analyze the risk factors of MS. Results The morbidity of MS was 34.75%. There were significant differences in weight , waist circumference , waist-hip ratio , frequency of dialysis , time of hemodialysis perweek , urea reduction ratio, urea clearance index (Kt/v), iron, intact parathyroid hormone (iPTH), leukocytes, high sensitivity C-reactive protein (hs-CRP) between these two groups (P < 0.05, resectively). Multivariate Logistic regression analysis revealed that iron (OR = 1.084, P = 0.042), iPTH (OR = 1.754, P = 0.035), waist-hip 1ratio (OR = 2.013,P = 0.021), hs-CRP (OR = 4.245,P = 0.000)were correlated with MS. Conclusion The morbidity of MS in patients with maintenance hemodialysis is higher. Iron, iPTH, waist-hip ratio, hs-CRP are potential risk fctors of MS for the patients with maintenance hemodialysis.

Objective To study the prevalence and risk factors of chronic kidney disease (CKD) among adults in Zhengzhou. Methods One thousand eight hundred and fifty five residents (≥ 20 years) from 4 communities in 4 districts of Zhengzhou city were randomly selected by using a stratified,multistage sampling. They were interviewed, and received physical examination and measurements of urine and blood for renal damage as well as risk factors. Results Eligible data of 1752 subjects were included in the study. After the adjustment of age and gender component, albuminuria was found in 5.78% of the subjects, hematuria in 8.19%, and reduced renal function in 1.58%. Male had lower prevalence of albuminuria and hematuria (4.37% vs 7.29%, X2=6.252, P=0.012; 5.08% vs 11.51%, X2=24.499, P＜0.01), but higher prevalence of reduced eGFR(2.26% vs 0.86%, X2=5.830, P=0.016) as compared with female. The prevalence of albuminuria and reduced eGFR increased with age. The crude prevalence of CKD was 14.50%, while the standardized rate was 13.57%. The prevalence of female was higher than that of male (17.83% vs 9.59%, X2=23.132, P＜0.O1), which also increased with age. The most common manifestations of CKD were hematuria and albuminuria. Gender, age, smoking, hypertension,diabetes mellitus, obesity and hyperuricaemia were independently associated with CKD. The awareness rate of CKD was 8.27% and only 7.09% of the subjects received treatment. Conclusions The prevalence of CKD is 13.57% and the recognition is 8.27% in urban adult population of Zhengzhou.lndependent risk factors associated with kidney damage are gender, age, smoking, hypertension, diabetes mellitus, obesity and hyperuricaemia.

Objective To investigate the role of ghrelin promoting proliferation of pancreatic β cells and the mechanism of it. Methods Mouse pancreatic β cells(NIT-1)were treated with different concentrations of ghrelin.NIT-1 cells proliferation was measured by MTT incorporation assay,and the cell cycle was measured by Flow Cytometry,and the expression of ERK1/2 and the level of ERK1/2 phosphorylation were determined by Western blot assay.Results With the increase of concentration and the time of treatment,ghrelin promotes cell survival of pancreatic β cells.The S-phase portion was changed after treatment of ghrelin on NIT-1 for 48 hours.The S-phase percentage in the groups where ghrelin concention change from 0 tO 10-9,10-8,10-7 mol/L were(34.5±6.5)%,(42.1±7.4)%,(50.6±5.8)%,(71.4±9.4)%,respectively.Ghrelin also induces phesphorilation of ERK1/2 in NIT-1 cell,and a doseeffect relationship was demonstrated.Conclusion Ghrelin could promote proliferation of pancreatic β cells through activating the MAPK/ERK1/2 signaling pathway and changing the cell cycle.

Aim To explore micro RNAs-integrated pathogenic signaling to control endothelial-mesenchy-mal transition ( EndMT ) in pulmonary hypertension ( PH) by a network bioinformatic approach. Methods Literature-mining method was used to find PH-relat-ed genes and EndMT/EMT-related miRNAs. Bioinfor-matic prediction approach ( DIANA3 , Miranda4 , PicT-ar5 , TargetScan6 , miRDB7 and microT-CDS8 ) was used for miRNA target prediction. Hypergeometric a-nalysis was used to predict miRNAs related to EndMT in PH. The analysis of interactions between PH-rele-vant genes( PH network) was performed with the use of Biological General Repository for Interaction Datasets ( BioGRID ) . These miRNAs were ranked with the highest probability of substantial overlap among their gene targets in the PH-network, the relationship be-tween their targets and the PH functional categories which include hypoxia, inflammation, and transforming growth factor/BMP signaling. Then, the part of results was validated by animal experiment. Lastly the miR-NA-Target network was built using Cytocape 3 . Results List of 230 genes was compiled that were directly im-plicated in the development of PH and 189 miRNAs were related to EndMT in PH. Among 189 miRNAs, only 22 microRNAs(miR-let-7 family, miR-124, miR-130 family, miR-135, miR-144, miR-149, miR-155, miR-16-1, miR-17, miR-181 family, miR-182, miR-200 family, miR-204, miR-205, miR-21, miR-224, miR-27, miR-29 family, miR-301a, miR-31, miR-361 and miR-375) were related to hypoxia, inflamma-tion, and transforming growth factor/BMP signaling. Among these miRNAs, the levels of let-7g, miR-21, miR-124 and miR-130 family were significantly changed in the pulmonary artery in hypoxia-induced PH rats. Conclusions Among numerous miRNAs,22 of which may be involved in hypoxia, inflammation, and transforming growth factor/BMP signaling and re-lated to EndMT in PH by network bioinformatic ap-proach, which provides a theoretical basis for further investigation of EndMT in PH.

Objective To evaluate the expression of CD4+CD25+CD127low regulatory T cells(Tregs) in the peripheral blood of the patients with NHL and discuss the relationship between expression of Tregs and prognostics factors of NHL.Methods 58 NHL patients was enrolled for analyzing.Among of them,23 were new patients without any treatment,35 patients received 3 to 8 cycles of chemotherapy,and 16 were normal controls.The expression of CD4+CD25+CD127low Tregs was detected by Flow Cytometry and the proportions of Tregs were analyzed among the groups of the patients before or after chemotherapy and the normal controls.Bivariate Correlation was used to analyze the correlation among the expression of Tregs in the peripheral blood and prognostic factors,such as age,sex,PS state,LDH,?2-MG,IPI,clinical stage and pathology category of the new patients.Results The proportion of Tregs in the peripheral blood of B cell lymphoma(B-NHL) group(3.89?2.49)% was significantly higher than that of normal control(2.52%?0.88%)(P=0.005).In B-NHL,Tregs was signifantly higher in the aggressive NHL(DLBCL,MCL) than that of nonaggressive HHL(FL,MZL)(P=0.002).In T cell lymphoma,Tregs was increased markedly in the highly aggressive T-NHL(T-LBL,NK/TCL) as compared with aggressive T-NHL(ALCL,PTCL)(P=0.006).Tregs expression was significantly higher in newly diagnosed NHL patints than that of normal control(P=0.004) and post-chemotherapy group(P=0.034).The expression of Tregs in peripheral blood was significantly correlated with ?2-MG,LDH and IPI of the patients in newly diagnosed patients group(P=0.003,0.003 and 0.038),whereas was not significantly correlated with the age,sex,PS state,LDH,clinical stage and pathology category of the patients.Conclusion The expression of CD4+CD25+CD127low Tregs in peripheral blood of B-NHL group was significantly higher than that of the patiens post-chemotherapy and normal control,which means that it may be an useful prognostic factor for NHL patients.

One hundred and twenty one patients on maintenance hemodialysis ( MHD) from Januaury 2004 to Januaury 2009 in our hospital were enrolled in the study. Demographic characteristics, clinical data and causes of disease were documented, the survival probability was estimated with Kaplan-Meier method and the prognostic factors were analyzed with Cox regression model. The median follow-up duration was 28. 9 months. The 1,3, 5-year survival rates were 93. 0% , 66. 5% and 45. 8% respectively. By Kaplan-Meirie analysis, cardiovascular disease (x2 =6. 582, P =0. 010) , age of starting dialysis (x2= 12.439, P= 0.002), urea clearance index Kt/V ( x2 =7.633, P=0.006) and albumin levels ( x2 = 4.512, P= 0.034) were closely related to prognosis. Cox regression analysis showed Kt/V, cardiovascular disease and age of starting dialysis were independent prognostic factors ( relative risk were 3. 204, 2. 994, 2. 543 respectively).
